I am currently working on (just started today) the hat and scarf Hermione Granger wears in the 6th Harry Potter movie. Luckily, I found the hat pattern somewhere, because I am sure I wouldn't have been able to improvise it. I am improvising the scarf and what I thought was going to be difficult has turned out to be easy, but complicated and makes concentration a necessity! I've never switched colors so much!
I have attached a pic with the originals so you all know what I am talking about!
